Technical Specifications and Features

This automatic transmission torque converter features a lock-up design that helps reduce slippage and improve fuel economy by mechanically linking the engine to the transmission at cruising speeds. The 11-inch diameter and 9.5-inch bolt circle ensure compatibility with specific GM transmissions. The 3-pad mounting type and absence of a drive on hub simplify installation and reduce potential wear points. With a 27 spline count and a pilot diameter of 0.825 inches, this torque converter fits a range of GM vehicles including the Chevrolet Cavalier, Pontiac Grand Am, and Buick Regal.

  • Buick Regal, Skylark, and Century
  • Cadillac models requiring a 27 spline lock-up converter
  • Chevrolet Cavalier, Lumina, Monte Carlo, and Corsica
  • Oldsmobile Cutlass Ciera, Cutlass Supreme, and Firenza
  • Pontiac Grand Am, Grand Prix, Sunbird, and Trans Sport

Common Issues Addressed by This Torque Converter

  • Transmission slipping or delayed engagement
  • Overheating due to inefficient torque transfer
  • Reduced fuel efficiency from non-lock-up converters
  • Vibration or shudder during acceleration
  • Failure of original torque converter components

Installation Notes and Tips

Ensure the transmission is properly drained and inspected before installation. Verify the spline count and pilot diameter match the vehicle’s transmission input shaft. Use the 3-pad mounting points to secure the converter evenly to the flexplate. It is recommended to replace the transmission fluid and filter during installation to maintain optimal performance.

Quality Assurance and Warranty

TC Remanufacturing torque converters undergo rigorous remanufacturing processes to meet OEM specifications. The B21FJ9 part is tested for balance and durability to ensure reliable operation. Warranty coverage details should be confirmed with the distributor or manufacturer, as terms may vary.
